Logstash WMI Input Plugin donot work

I am new to logstash and i want to gather the performance metrics of the windows system. I have been trying to run the WMI input plugin of logstash in my local setup to gather data, but it is not getting executed .This is the logstash configuration.

input {
       wmi {
        query => "select * from Win32_Process"
        interval => 10
		host => ""

output { 
	stdout {codec => rubydebug} 

i can run above query in the powershell and i get the data. Below is the error logs i get when i run the logstash.
